"Something went wrong during slicing"

[olivierc 3]

Help me Daid or anyone!

I'm trying to slice a model in Cura, a big one for a big print, but after about an hour of calculation, I get an error message saying something went wrong during slicing, and the model has disappeared. I tried twice and it happened both times.

My model is very clean I think, I spent a lot of time doing all kind of check to make sure everything is closed, merged and fully manifold.

Here is the log. I can see the last line says Memory Error. Does that mean I ran out of RAM? because I still had plenty, I sliced this at work where I have 12 gig of memory, on powerful. The model is "only" 200000 poly. Sure it's a lot, but it's already optimized and necessary for the sculpture I want to print. I have sliced models with more polygons that this before, but they where not as big in term of volume.

Maybe I'm missing something form the log, some operation that might have generated this memory error, like a division by zero or something. If someone want to take a look at the model itself, I can post it.

I'm using version 13.04, not the beta. I have sliced many models in cura, some more complex, this is the first time this happens to me.

MemoryError

It's a 32bit application, which means it runs out of memory after consuming 2GB of memory. (The amount of memory is not only related to the amount of polygons, but also to the internal volume of the model)

Checkout the Cura BETA thread, it contains a link to the 13.05 testing versions, these are much more suited to slice large models. I've sliced things up to 3000 layers on 500k polygon models without issues.

awesome, I'll try that tonight. I was waiting for the stable version. Does it performs at least as well as 13.04?

 

[olivierc 3]

I tried at work. Nice, sliced it in 5 minutes ! Looks like I'm not moving to kisslicer. It's predicting a 30h print :???: Never tried to print anything longer than 7 hours, wish me luck

 

[Daid 305]

Yes, I consider it as stable as the previous version. But at the same time I'm a bit careful in releasing it as "main" version. It has quite a few new things under the hood that could cause issues.

Cura 13.05 testing version .....

We've been using it on all our UM's ... haven't found a bug or glitch yet ...

just want to state once again what an awesome improvement Cura has undergone .... Kudos ....
